Presented by Jeff Vautin and Joe McCabe of Bose Automative Systems
On Monday, January 21st, Jeff Vautin (PAT Graduate) and Joe McCabe from Bose’s Automotive Systems division visited the University of Michigan chapter of AES to give a presentation about designing acoustic system for vehicles. A car is one of the harshest acoustic environments for an audio system; it has simultaneously very reflective and very dry material, and the small space introduces harmful standing waves. Mr. Vautin and Mr. McCabe talked about the techniques Bose uses to get around these challenges to produce the best audio quality possible, ranging from optimal speaker placement to the different digital signal processing methods used for different speakers throughout the car.
Learn about Sennheiser and Neumann’s digital microphone technology through an interactive hands-on workshop. This workshop will show how these digital mics work, what makes them different and the various applications they can be used for. We’ll also listen and compare them with some of their analog counterparts to hear differences and similarities with live musicians in the studio.
Christopher Spahr oversees national market development for the live sound and studio markets for Sennheiser, and works as an independent producer/engineer. During his 17-year career in the recording arts and installed sound industries, Spahr has performed live sound work for concerts, corporate functions and theater applications. He also worked in the installed sound market as an independent manufacturer’s representative and spent five years as a staff engineer at Criteria Studios in Miami, FL working on music, TV and film projects, including a Grammy-winning Latin jazz CD.
Spahr is a certified member of Sennheiser’s U.S. RF Expert program. He holds a B.S. in Business Administration from Barry University and a Recording Arts Specialized Associates Degree from Full Sail University.
Ableton Live is a dynamic and empowering tool for every stage of the musical process, from composition to production to live performance. Whether you are a producer or dj, sound designer or composer, the versatility of Ableton Live makes it the ideal tool for both beginners and experts alike.
Yamaha’s Martin Dombey will be coming to speak on the “Principles of Digital Mixing for Sound Reinforcement Applications”. He’ll be bringing a couple of Yamaha’s flagship digital consoles and demonstrating their practical usage. You can learn more about Martin Dombey by reading his bio here.
We are welcoming all who are interested to our last AES event of the year. We will meet in McIntosh Theatre where Meyer Sound will be giving a seminar on the fundamentals of system design.
The Fundamentals of System Design seminar encompasses a variety of topics in sound system applications. Practical information about AC power, grounding, hum, gain setting and polarity are presented in a real-world context to provide useful background. Theory and practice of line arrays are discussed, along with tools for system optimization, including equalization, delay, loudspeaker management systems and measurement with the SIM 3 audio analyzer system.
The seminar’s second day is dedicated to use of Meyer Sound MAPP Online acoustical prediction software as a primary tool in system design. After an extensive introduction to the program and its capabilities, attendees are walked through exercises in which they specify venues and design loudspeaker systems to cover them.
Finally, the seminar will discuss and demonstrate important concepts pertaining to the use of subwoofers and methods of deployment that obtain optimal coverage and directivity characteristics.
The goal of PTF is nothing less than a full set of objective measurements of an audio system that correlate with perceived performance. Rather than attempting to map conventional measurements to perception, PTF uses all-new stimulus, reception and analysis techniques. PTF is organized into test modules that are selected from a Virtual Instrument (VI) computer interface. Each module tests an aspect of audio performance that corresponds to human assessment: Tonal Balance, Imaging, Maximum Loudness and Distortion. Each stimulus signal is generated by the VI and converted to an electrical signal by the hardware. The signal is sent to the system under test and received by the PTF microphone array. (more…)
Jeff Vautin is currently a fourth-year student at the University of Michigan, studying Sound Engineering and Electrical Engineering. He recently completed an internship with Shure, Inc. working in their analog circuitry group.
In addition to hearing Jeff talk about his internship experience, representatives from Shure were here to speak with students about upcoming internships and jobs with Shure and answer questions about applying to and working for the company. Shure also hosted a pizza party after the talk.
